Thanks, Hans, for your advice.

I could edit the font features, indeed, but I run a GNU/Linux OS, and Fontforge cannot edit nor generate variable fonts. There seems to be a solution (https://www.youtube.com/watch?v=xoQuWARCUWI ), but so far beyond my technical capabilities that I cannot consider it.

Yes, it is, but not from the beginning. A great Garamond, the original font was designed by Georg Duffner. A few years ago, Google decided to make it a more complete font family : Octavio Pardo has done an excellent job with the bolder versions of EB Garamond and its conversion to a variable font. However, for whatever reasons, he did quite a rush job with the OpenType features ! Many essential features are lacking (despite the needed glyphs still being there), and most present features are poorly implemented, with a lot of typographic nonsense (concerning long s and long Q or the mentioned italic ligatures, for instance).

I will contact Google Fonts shortly to report on the dozens of problems I have encountered that make the unfixed new version of EB Garamond unusable for anything but the most basic uses.
Fortunately, my significantly more demanding needs for a client were met with the invaluable help from LuaTeX, but that won't be enough for my own projects, much more complex (facsimile of ancient editions), until Google improves this font.
